You need to use in Joomla 1.7 teh Keycaptcha is not free . That means also your web have delays reading the keycaptcha server is never google recaptcha.
I am interest in speed and functionality but I no get that with that component
Yes, now Keycaptcha is the only option for Joomla 1.6-1.7. The "trick" is simple: their team was the only one to collaborate with me on the subject; other earlier compatible captchas were not updated for Joomla 1.6...
We are lucky Joomla 2.5 will have Captcha support in a core. I will definitely allow yvComment to use that core Captcha plugin.
Funny but is like a part of your template with not any function . I send a email to support but never get reply. What I go to say nice simply module but not working at all
Thank you for your feedback, did you have install on joomla 1.6.x? Can you resend you question to my email: email@example.com because on support page we couldn't find your previous email. That's the reason why we are unable to give you an instance support.
About the no send emails, thats not right because we're using on the joomlavi.com and other site and it's working fine. Let me test more site and if find your claim problem is true, we'll fix it immediately.
About Captcha: your hosting have support GD2? maybe thats problem, GD2 is available on almost website hosting, please check yours.
So we have already made update version for this module with some new functions:
1. Add custom field
2. Fixed bug captcha
3. Add a component too
4. The lables input text option (inside/outside text box)
Look forward to hearing from you soon.
